Williamson, selected out of Duke last month with the first overall pick in the draft, suffered the injury in a game against the New York Knicks on Friday night in Las Vegas.

“Zion will move forward from this incident without issue,” Griffin said in a statement released by the Pelicans. “However, in an abundance of caution, we have made the determination that he will not appear in game action for the remainder of NBA Summer League.

“He will continue to take part in training and conditioning with our performance team.”

Williamson had 11 points in nine minutes in the 90-84 Pelicans victory over the Knicks.
